The recently renovated AT&T Center in Los Angeles, formerly known as the Transamerica Center, has received the first gold-level certification from the U.S. Green Building Council for an existing downtown building.

In 2007, Elleven, a downtown condominium tower completed in 2006, was awarded
gold-level certification for new
construction.

AT&T Center's owners also announced today that restaurateur Patina Group will move its headquarters to the 32-story main tower at 1150 S. Olive St. and open a restaurant on the ground floor. AT&T Center, which also includes an 11-story building at 12th and Hill streets, recently underwent a $35-million renovation that incorporated upgrades to its power and water systems to make them more environmentally friendly. More noticeably, the makeover included new metallic facades around the buildings and an illuminated glass enclosure on top of the tower that added two floors of office space.

The skyscraper was the first in the city to surpass City Hall in height when it was completed in 1965, and for decades it had a restaurant and bar on the top floor. With that space now converted to offices, the Patinaâ€™s Groupâ€™s new restaurant is being planned for street level.

Patina Group has agreed to occupy 30,000 square feet, according to landlord LBA Realty. Another new tenant will be Fox Entertainment Group, which has rented 25,000 for its cable sports division.

"The property is near Staples Center, home to many of our professional sports broadcast affiliates," said Steve Simpson, a senior vice president at Fox.

The Patina and Fox leases will bring the buildings to 85% occupancy, said Perry Schonfeld, a principal of LBA Realty.
